In our video about tire sizes, we mentioned that the vehicle had the wrong tire size on it. We did not talk about what that will cause and what it can mean for you as a driver. In this video, we dive into the math behind how incorrect tire sizes cause your speedometer to read incorrectly

Actually this prof is wrong he shouldn't multiply the rpms that he saw on the small tyre to the large tyre to get wht the odo will show. What actually will happen is the rpm will be less. As the tyre is larger its circumference is larger thus it needs less rotation to cover the same distance as a smaller tyre. Thus there will be a lower rpm recorded on the wheel. Which the computer will percieve as lower distance and speed. Thus u get a false lower reading. Not high!! So much for a tyre prof😅 i knw he is not a prof.😝 But sure wud pass for one

The more important point is that the wrong size of tire can show that your car has more miles on it than it actually has. A smaller tire over 6 years can really mess with the odometer. Not to mention this throws of your service schedule. Oil changes etc. I guess you could put larger tires, notate the difference so you don't speed and keep your cars mileage low. lol. Thanks for the video.

My 2020 Mitsubishi Outlander PHEV OEM's are 215/70r16. I changed it to 225/70r16 AllTerrain tires (I do a lot mild off-road, gravel roads and snow). I am very happy with the change but I lost about 20% of EV range and fuel consumption went slightly up. I will be performing 1.2inch (about 3cm) lift and I am planning to install even bigger 225/75r16 tires to increase the tire side wall and ground clearance even more. Do you think this is good idea or this is too much?

I think the more concerning issue is how the tire size affects the longevity and performance of the car, in my opinion. Also, I heard most cars of today have their speed set lower than what their speedometers display. Using my car app such as Waze, I can notice my speed in some cars to be 2 to 3 miles lower than what is displayed in the dash. So, in this case, should I still get a tire that is bigger than what is specified for my car?

The middle number is related to the load the tire is carrying. Going down on the number, such as 75 to 50, can cause the load to exceed what the tire is rated for. The first three numbers are just the radius from the rim to edge of tire. Going too high create problems with rubbing and going too low can bring the car dangerously close to the ground and damage it. Last two numbers are for the rim size. You can't change this without getting the proper size rim. Otherwise the tire won't seat on the rim.

Got a BMW 335i. Went through 17 tires in a 3 year period. Therefore, I had zero confidence in the reliability of the vehicle. Well, ironically enough, I garaged the thing for 2 years bc I was sick of driving somewhere, blowing out a tire and then waiting for AAA to come give me a tow bc the vehicle has no spare. Well, after taking it out of the garage recently, I realized that the back tires (which calls for a larger width) was the same as the front. So these dipsticks at NTB we’re sticking on the wrong size for 3 years. No idea how I never caught that. So, shame on me for trusting someone else that should know their job.

Nice to see your method of displaying the calculations. I myself have simply ignored my car's dinosaur terrestrial speedo'... for over 15 years, in favour of GPS! Reason: my '91 seven seater FrontWheelDrive (FWD) mazda's speedo has an inbuilt inaccuracy far beyond what I personally deem practical; for example at Speedo 100kmh, I am doing GPS 92kmh. At Speedo 80, I am doing GPS 73kmh etc etc. The vehicle has only one size on it's manufactures' chart - being 185/70-14. I'd like to go for 185/75-14 instead. ( I don't want to go 195/65-14 etc etc) I want to achieve a longer rolling distance; smoother ride From the above figures: PROs: I will have no need to worry the Speedo will ever under-read, compared to the GPS' as according to calcs' I would expect to see a 3% increase in Rolling Distance with the 75% tyres on. I can see I would achieve a softer ride; lower RPMs for any given GPS speed; I don't need to worry about larger wheel rim width changes; I would achieve a higher area of footprint for better hold, for, when applying power I therefore expect to never again have to suffer the tyre skid when accelerating from standstill. This being due to the extra rubber on the road, from the larger Diameter. CONs: There might be some small compromise to tyre wall deformation upon hard cornering? An Insurer might refuse to pay out, if the tyre is not exactly as stipulated on the Plate? My Mazda seven seater is FWD, and is well known for the tyre skid upon acceleration from standstill. Most of it due to being FWD, but I also have long blamed the original diameter of a 185/70-14 contributes to it. A more modern vehicle's ECU would report to the owner that it's next due Servicing Schedule would for example come due at 97000km instead of 100000km

This is good stuff, BUT just the tip of the iceberg as many here are here because we go with larger tires because we're modifying our vehicles to perform better off road and we're curious how to manage the differences with MPH, fuel economy and power..... For instance, I have an '04 AWD Astro van I converted to 4x4 with an s10 transfer case and I have a decent lift on it. My tires are now about 2" taller than stock and my speedometer is off 4mph... There are charts out there that point out the relation to tire size, gearing and rpms - There are "sweet spots" to aim towards, for instance, according to what I've seen you can get better gas mileage but have a loss of power at the same time. This video is great for what it is but most people who go with larger tires already/quickly learn/understand the speedometer is off without needing to understand the math involved (I enjoyed this explanation, anyhow) - What they really want to know is how to reprogram the computer to work with the new tire size so the speedometer in in sinc as well as to get the mpg readings to be accurate - I'll be looking to see if you've done anything on that as I believe you'd probably be the perfect guy to explain all that

Thank you for taking the time to watch the video and for your comment. If they put those tires on the vehicle, but not on all 4 wheels, then it absolutely could cause your AWD system to act funny, and to drive funny. It can also cause damage to your AWD system. If all for wheel had the same size put on, it's less likely that it would cause problems, but some vehicles are capable of detecting when the incorrect tire size has been installed. Best of luck and I hope it turns out well for you.

The manual just says it's a tire rotation problem/difference between the front and back tires. Maybe they aren't all the same tread or maybe I need to add air.

Immediately realised as I drove off the xtra effort it takes to pull away, not a lot, but still. So by his logic it would also mean that a car would have less miles on it's tachometer than it actually travelled if fitted with bigger tyres, right?

After punctured the tire (pothole) I was in need to install spare tire, so I could only get in that situation 225/50/17 tire (other three are 215/50/17). One wider tire installed on the rear right position. I'm in the process of finding the same 215/50/17 tire, and occasionally driving with one wider tire (and with different pattern), and I didn't notice any change in control, balance, braking, also in 6th gear on highway. Do I really need to match one wider tire ASAP? What are the symptoms of driving with one tire wider 10mm than others on the system? Thanks.

While an old video, it's my problem today. Bought a 2023 1500 RAM. Dealer put a front level on it and Firestone Destination 35 12.5 r20 on. Seem to be great tires. I drove a few hundred miles, speed seems off, WAZE gps shows 44 while truck shows 40. I went back to dealer, did ya calibrate these tires? Nope, RAM won't let us. SON OF A !! I went to a tire dealer, nope, they can't but down the street will. I went there, come back for a quote! WHAT? Ya put a box on, say size of ture, poof fixed?? He believed the price would be about $800 as they take the dash off. OH HEY THE H NO YOU WON'T!!! So, I have wrong odometer miles ,wrong shifting speeds, wrong mpg, wrong mph, and I'm cheated from my warranty mileage as I believe I have driven less than the bigger tires register. I should have 275/55r20 but dealer put on 35 12.5 r20- what's that- some 4 to 5 inches more diameter? Thanks for a good video.

Ok so if I take a truck with a 30” tire already on it and that tire rotates 622 times in a mile. That same truck I put on 50” tire that rotates 404 times a mile. But of course because the bigger tire has a bigger diameter, the engine struggles and the Speedo is wrong. What if I put on portal axles with a low gear ratio to counteract this? Then my speedo is correct and my engine has the same mechanical advantage with the 50” as it did with the 30”. Yes I know the 05” will be heavier and cause the engine to struggle more, but I’m ignoring that for the time being. What do y’all think?

That might appear that way. But in Reality, the factory tire size that comes with a vehicle is thoroughly tested to be the best possible for the vehicle, engine, aerodynamics of vehicle and offcourse driver comfort. If increase diameter increase mpg, then all companies will fit bigger tyres lol, to increase mpg. The tyres with bigger diameter cost more engine power thats why truck and suv with bigger engine has bigger diameter tyre than sedan. If u install suv size tyre in a sedan with 40mpg, the mpg will drop cause taller tyre will push engine to use more power and therfore use more fuel. And yes top speed of vehicle will decrease as well. The handling might also be bad.

Do TIRE differences harm a transmission?
@simonjmeyers
@simonjmeyers 2 жыл бұрын
This is an old question but I'll answer it for the next guy because its a good question. Short answer is Yes. If you have mis-matched tire sizes on the driven axel (front wheel drive/rear wheel drive) it could definitely cause problems. If you have two different sized tires they will have to spin at different speeds to cover the same distance, kinda like when you go around a corner, the outside tire has to spin faster than the inside tire. This is why cars have differentals. If youve ever driven a car with a Locked/Welded Diff and go around a tight corner it basically forces the inside tire to do a supsr slow burn out to keep up with the outside tire. So it'll probably burn up the Diff before the transmission? I cant imagine a front wheel drive with an automatic transmission would fair very well either. Its absolutely necessary to have 4 matching tires with any All Wheel Drive system where its AWD all the time. Subarus are kinda notorious for making people change all four tires at once even if you just had a random flat in one tire for fear that putting a brand new tire on one corner when the other three are maybe only halfway thru their thread wear. BMW X-drives ive heard similar. So really as long as the two drive tires are Same size, the actual size is basically irrelevant.

The taller wall tires will give more comfort. One will have to bear in mind that the actual road speed will be about 3 to 5 percent higher than the speedometer reading. I think as long as the wheel well can fit, upsizing the whole tyre is doable.

most car speedometers are calibrated to show 5-8% more than your actual speed so people can't blame the speedometer when they care caught speeding. so an inch up should really not make a big difference since you would still be traveling slower than the speedometer says. If you want to measure precise speed GPS is the way to go.

I can't say confidently one way or the other. With taller tires, your vehicle will work a little harder, but go a little further. I'm not certain which way would yield the best MPG. But thank you for your comment and for checking out the video. I might have to investigate that in a future video.

I just had two sizes bigger tyres fitted on my car. Was advised to do that to better handle an unpaved road I have to travel daily. I immediately noticed I needed to give it more gass to pull away and that the fuel consumption is a little worse, not too much, but noticeably so. The ride comfort improved, which is what I needed, and I have less road noise, but all other aspects remain unchanged. Cornering , braking etc. But then again, Iam just driving normally, didnt do any top gear style performance tests.

I have a question I have a 2019 Nissan frontier 2.5 King cab. The tires are small with the s model the SV King cab with 4.0 V6 have bigger tires. I just wanted to see if I can go up a little higher like the SV model of the King cab Nissan frontier but I'm kind of skeptical about doing it after seeing these videos. I just want a more rugged look because it sits low to the ground and I would like it to sit a little higher

As far as fitment goes, they would very likely fit just fine. Those tires will be just shy of 1 inch taller than the tires you should have. My concern is that you said the front, which makes me think you are talking about only replacing the front. You want to avoid putting different sized tires on the same vehicle unless it was designed to be that way. While the tire might fit and work fine, the different size will make those wheels turn slower, and having that happen can cause a number of ABS issues as the ABS constantly monitors all wheel speeds and uses that info, along with other input information, to determine if the wheels are locking up. In addition to that, I thought thoust 740li's were AWD, or at least some of them were. If it's AWD, you absolutely never want to put different sized tires on unless you're putting all 4 on. On AWD vehicles, you'll tear up the drivetrain if you have the front and rear axles trying to turn different speeds due to different tire sizes. I would suggest either finding the recommended size for your front tires, or replacing all 4 with the 245/45/20 tires you found.

I do understand the millage and speed difference and that is not a concern. Do I lose anything essential otherwise and my question is actually for a reverse scenario, say using an aspect ratio of 65 instead of your 70, with the aim to bring the center of gravity a bit lower in a sporty car and not a truck, for better cornering? Will, I jeopardize something significantly, or am I at fault by a liability on any major issue?

Rainier Dagdag. Ok, with just a quick check, you should come out close to the same diameter if you use 175/50/R17 tires. Your stock size is 175/70/14. This is if you want to stick with the same width of tire. But that's a rather odd size and finding tires that size and buying them may be more hassle than you want. Another thing to consider with putting aftermarket wheels on is the offset. Most aftermarket wheels carry a different and greater offset than your stock wheels. This means the centerline of the wheel will be at a different place than with your stock wheels and tires. If the difference is too much, you can end up with wheels that rub the liner or suspension parts on turns. I'm not trying to talk you out of aftermarket wheels, just do a lot of research to make sure they'll work the way you want them to once you purchase them.

Hello, thanks for explaining the difference in such detail, I got new tires from discount tires for my 2006 Chevy HHR and the guy screwed up ordering my tires and instead on ordering 215/50/17 he ordered 215/55/17 which is a bigger tire. I really don't care about the speedometer or the odometer readings, I was more concerned about how this will affect my suspension because there is really about half an inch distance from the new tire to the suspension plate.. Also my other concern is the gas mileage and how it would have an affect? Thanks in advance..
